I freed 30GB using Filelight

Personally I'm a huge fan of dust

I freed 50gb by running 'docker system prune'...

last year I had over 1TB freed by docker system prune on a dev VM. If you're building images often, that's a mandatory command to run once in a while.
- I create a cron job with something like: docker system prune -af --filter="until=XXh" where XX is on the order of a few days.
I'm new to docker and all of my shit stopped working recently. Just wouldn't load. Took about a half hour to find out that old images were taking up about 63GB on my 100GB boot partition, resulting in it being completely full.

I added the command to prune 3 month old images to my update scripts.
- Yeah, it's really not called out in the docs. I found out the same way.
I once freed 28 GB using find ~/Downloads/ -mtime +30 -delete
paccache -r got me about the same
Oh hey thanks for reminding me, freed 5GB which should buy me a bit of time on upgrading the server I use for this lemmy instance.
Oh, that reminds me,...

Personally I'm loving diskonaut. "Graphical" representation but at, ahem, terminal velocity.

Jesus, that rustup folder is HUGE
- One of the things I dislike about Rust is the massive amount of disk space and time it takes to do a download, compile, test run.
  2GB of dependencies and build files for a 200K binary is a bit much.
Linky pls

  No package for my distro, I "installed" an AppImage with AM (which is also how I discovered it)
I use dua, but this looks neat too.

Clean all the cache downloads of Arch Linux Packages

pacman -Scc

Remove unused docker networks and images

docker system prune --all

Cleanup untracked git files that might be in .gitignore such as build and out directories (beware of losing data, use "n" instead of "f" for a dry run)

git clean -xdf

Do an aggresive pruning of objects in git (MIGHT BE VERY SLOW)

git gc --aggressive --prune=now

Remove old journal logs, keeping last seven days

journalctl --vacuum-time 7days

Remove pip cache

pip cache purge

Remove unused conda packages and caches:

conda clean --all

If you are a Python developer, this can easily be several or tens of GB.
I can see you're not using Flatpak, the destroyer of disk space. Nice list though!

My dad's Linux setup couldn't log in. After a bit of investigation, starting the session manually and so on, i got a hunch and indeed; i saw in Baobab that the backup script took the wrong disk, filled up the one with home, making it slow, so the log-in thingie timed out, failing the session.

I normally use rm for that. Or wipefs if I'm feeling particularly spicy.

Filelight is about finding the folders you don't use that take a lot of space. Basically an easier way to look into which folder takes up what.
- Wooosh 😉

No one showing love for ncdu around here?

Ncdu is my go-to tool. Can't live without it on the servers I administer. However from this thread I've also learned about gdu, diskonaut and du-dust that I need to check out.

A bit too much to just install one soft. Hard pass.

[moonpie@osiris ~]$ du -h $(which filelight) 316K /usr/bin/filelight

K = kilobytes.

[moonpie@osiris ~]$ pacman -Ql filelight | awk '{print $2}' | xargs du | awk '{print $1}' | paste -sd+ | bc 45347740

45347740 bytes is 43.247 megabytes. That is to say, the entire install of filelight is only 43 megabytes.

KDE packages have many dependencies, which cause the packages themselves to be extremely tiny. By sharing a ton of code via libraries, they save a lot of space.
- It being KDE is even less reason to use it
That's very normal if you don't have any KDE apps. If you were using KDE and installed a GNOME app it'd be similar.
It's a KDE application, yes.
You could try baobab instead.
Looks like the depends list of the average KDE app on a none KDE system.
Lol I had no idea it relied on so much. Its just built into KDE. Really great app overall.
- Basically all KDE apps have the same dependency set. So install one and the next ones will only install the app most likely. On KDE itself you'd already have these.
My little widget to get the weather, Blazing Fast Uber Duper made in Rust, has like 85 total dependencies from like 3 crates that I need...

My own software is a hard pass for myself...

That's great!

Another thing that is great, since we are talking about disk space: people, check your Rust repositiry, it might be huge.

I deleted that folder and, in my case, freed 12gb. Not too shabby.
flatpak install flathub org.kde.filelight
On gtk desktops it's something like Baobab. Too sad that the big guys can't make lightweight and standalone software.

this looks exactly like gnome disk usage analyzer

I freed my entire disk by removing the French language pack

I recommend it too. It's simple as doing:

sudo rm -rf /

Where "-rf" obviously stands for "remove french".
- The joke goes rm -fr, which stands for "remove french". Yours has double "remove" and is less believable.
- (This is a joke don’t do this or you’ll ruin your computer)
- @MrSoup @bricked
  I know but was was the parameter for 'force recursive' ?
For the curious, rm -fr /

The always huge and killing my system space:

pacman cache
docker bullshit
flatpaks
journalctl files!

In case you don't already know about it, paccache (part of the pacman-contrib package) will let you easily remove old packages from the pacman cache

I'm more of a baobab person myself 😋

Isn't it the same?
- Basically, just using gtk instead of Qt :P

dust

Yes, it's du in Rust + more.

Isn't that a wayland notification daemon already?

Edit: no, that's dunst.

Btw, how do you do the background color thing?
- Now someone needs to do a rewrite of dunst in rust called runst to make the confusion complete.
- I was confused what you meant by background colour thing so I went to dust docs haha.
  
  Now I got you. It's a codeblock so it shows in monospace font. Look up .md formatting for tips.
  
  In this case its a word between backticks `
Came to recommend du-dust!
I have to remember to check this out. its on my reminders in my self host calendar but its been offline fpr quite some time after moving.

Excellent! I missed DaisyDisk. It looks great!

GDU: http://i.xno.dev/u/WWyrND.png

i use https://dev.yorhel.nl/ncdu for this

Also dust
I'm à qdirstat guy : https://github.com/shundhammer/qdirstat
- I believe FileLight (in OP above) is a fork of or built on top of QDirstat.

This is why I've set up a ramdisk on ~/.cache and ~/Downloads -- "free" automatic cleanup plus a tad more of performance because why not.

I might do that just to force myself to organize and move files out of downloads.
- I don't think you'll need to do that, unless you are planning to download files that are over 4Gb long and/or you are using a potato that has less than 1 Gb of ram.
  
  t. I've set my entire ram into a ramdisk, and the performance actually IMPROVED compared to not setting a ramdisk at all.

I use du -hs * | sort -h

In Germany "du hs" is considered an insult and I think that's beautiful.
- selber hs °^°
du -sxk | sort -n gotta find those hidden files too!
This tool is amazing https://github.com/KSXGitHub/parallel-disk-usage
duf is pretty slick
If you need a more interactive method, gdu is awesome. And if you're using btrfs, btdu gives preliminary results instantly (which get more precise over time).
- I'm getting old...KISS!

I love Filelight. Whoever came up with it is brilliant.

Is this a Linux version of windirstat?

There's also QDirStat which is like KDirStat but without KDE dependencies.
There's a more direct version of that, I guess from KDE, called KdirStat.

I hadn't heard of the one in the op. But if I had to guess, it looks like it's a different take on the same idea.
- Omfg.
  
  I was trying to remember the name of kdirstat ladt night when I stumbled across filelight and made use of that instead.
  
  And now there's a thread on this exact topic. Y'all need to quit it with all this Truman Show nonsense, Baader-Meinhof alone isn't enough to explain how frequently shit like this happens. XD
side note: wiztree performs better on windows than windirstat, radically faster scans

now I feel dirty talking about windows here..
- There was something about wiztree that kept me using windirstat. I don't think it's free software.

I like Bleachbit but I'll check this out

I use gdu personally

gdu gang

Those are rookie numbers.

I'm here to promote fclones. I've used it twice and recovered over a terabyte on my NAS the last time I used it. I'm not affiliated. Hyperspace for Mac is similar (but different) and I haven't used it, but it was developed by my favorite nerd podcast host. I'm planning to test it out eventually, but the latest fclones run was only about a month ago, so it doesn't make sense to try it yet.

Fclones is a great tool, but it's for finding duplicate files and replacing them with sym-/hard-/reflinks.

I recommend using the --cache option to make subsequent runs extremely quick.
- --cache option
  
  I will check this out!

Looks like a worse looking baobab clone

My / is a tmpfs.

There is no state accumulating that I didn't explicitly specify, exactly because I don't want to deal with those kind of chores.

These tools are also useful for finding large files in your home directory. E.g. I've found a large amount of Linux ISOs I didn't need anymore.

Does Linux have spacesniffer?

No, and I miss it. Space sniffer was so good.

That's when you know it's time for a fresh install

Nah, in a rolling distro it's normal, they were mostly unused stuff hide in /home, and useless yay pkg.
Sir, this is not Windows.
- I'm still pretty new to Linux so I break stuff pretty often, like recently I was trying to get opencl working with my amd gpu and I ended up causing every video I played to stutter constantly.
  
  And I've been trying out new software to control fans or rgb and following guides making me enter commands until I figure out something that works I note it down so when I do a fresh install again I can easily configure it without all the trial and error etc and install only the software I found that I liked
  
  That plus distro hopping
Do you delete all your files on a reinstall? Documents, photos, videos, games?
- Separate partitions for / and /home, save all your data, configs, etc. but you can still distrohop!
- I usually keep important stuff on my server but things like games and stuff I purge with the fresh install and just download the games I'm actively playing, also helps clear up any issues from installing random junk during the months between as I settle on what programs I like
